[BF6] Rubberbanding and Lags - knwon also from other titles

Hey folks, i have a problem, which occurs in many Battlefield Titles but now annoys me very much at BF6. I have many Rubberbanding/Lags. Sometimes more, sometimes less. I can not locate on what it depends. My friendy i play with doesn't have problems at all with this.

• Hardware is not overloaded, no temperatureproblems
• Internet connection is stable and bandwith big enough
• In BF2042 i was able to check In/Out Bandwith and Packetloss to the BF Servers, there i never had packetloss.
• Router is a very new one without custom port restrictions
• Nothing else than BF6 and Discord is running

Hardware: i9-12900K, RTX 3080, 32 GB RAM DDR4

Any tips or recommendation/advises?
